TUFT-MAKING MACHINE.

i Tc all whom z' may concern Be it known that l, DANIEL L'. CHAHDER, a citizen of the United States, residing at Ayer, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Tuft-Making Machines, of which the following is a specilication.

This invention relates to improvements in brush making machinery and particularly to a machine for making tufts for brushes, and has for its object to provide a machine of this class which shall automatically'take a bunch of bristles from a mass', double the bristles transversely, insert the tuft thus formed into a suitable holder, andfasten the tuft in the holder.

A further object is to provide means whereby the bristle holder may be made from` a continuous piece of tubing.

Another object is to provide means tol remove the bur or chamfer the insidevof the end of the tube into which the tufts are to be inserted, y

Another object Vis to provide improved means for feeding the bristles from the mass and forming them into loops.

- Another object is' to provide'a novel means for operating upon/chel bristle holders to secure the bristles therein. t

A still further object is to provide means to eject the finished tufts. l

To these ends, my invention consists in the novel features of constructionl andinu'the combination and arrangement. of parts set forth in the following specification and particularly pointed out in the claims.

Fig. 20 is a front elevation of' all four dies, illustrating their cooperative action upon the' tube.

Like numerals refer to like parts throughout theseveral views of the drawings.

In thejdra'wings', 21 is a main driving shaft journaled in suitable bearings 22 and 23 on a base, or frame 24 and having a driving pulley 25. From this shaft mostof the mechanisms of the machine receive their power.

Bristlc' feeding and tuft forming mecham'sm. (See Figs. 1, 4, 8, 10 and'll, particularly Figs. 8, 10 .and 11.)-A hopper 26 for the bristles consists of two lwalls 27 and 28 provided, respectively, with grooves 29 and30 constituting ways to receive a weight 31 arranged to slide vertically therein. This weight 4which serves to crowd the bristles downwardly in the hopper may be provided with one or more supplementary weights 32 mounted upon an upwardly extending rod 33. The hopper has a back wall 34 on one side and the mass of bristles is inserted in the hopper, as show-n in Fig. 8, with the ends of the bristles against the wall 34, as illustrated in Fig. 8. The weight 31 is then put in place so that its lower end rests upon the central portion of the uppermost bristles, being understood, however, that when the hopper is loaded it will preferably be loaded with a greater mass of bristles than is shown in the drawings. A fourth wall 35 extending part way up the side of the hopper serves to'confine the ends of the bristles at that side. This wall is preferably rempv-l able in order to facilitate the introduction of the mass of bristles and tojthat endv is mount-ed to slide vertically and is supported upon two screws 36 and 37. The hopper 26 which is otherwise open at the bottom is providedl with two downwardly curved depending guides 38 and 39 so shaped as to guide the bristles to the lower'- most point thereof where theyV are to be engaged by the feeding devices. Preferably, the bottom of thev weight 31 is provided with a V-shaped'notch 40 so formed as to facilitate the crowding ofthe bristles toward the lowermost point of the guides 38 and 39.

The lowermost bristles' of the massfin the hopper rest upon a bristle carrier -41V in the manner shown Figs. l'8, 10 andll. This bristle carrier-consists of tworplates 42 and 43 separated by av space 4in which is located a plate 44 carrying at 'its upper portion a very thin plate or needle 45 provided at its. forward end with a notch or recess 46 designed to engage the bristles as they are crowdedy down into a recess or I -throat 47'provided inthe upperside ofthe plates 42 and 43' of the bristle carrier 41. Preferably, the size of this recess or throat is varied by means of two adjustable plates 48 and 49, see Figs. 10 and 11, secured to op osite sides of the bristle carrier 41. The bristle carrier 41 is provided with a longitudinal passage 50, preferably cylindrical in form, communicating with the recess 'or throat 47 and also communicatingfwith a slot l51 in which the needle 45 rec1pro-' said needle also extending up in to cates,

as clearly shown said cylindrical passage, in Fig. 8.

The plates 42 and 43 which constitute the bristle carrier 41 are secured to a slide 52l mounted to slide on a suitable' gulde 53 provided on a bracket '54 mounted on the as shown in Fig. 8, it

' base of the machine. This slide isrecipro# cated at the proper times in the operation of the machine by a cam 55, see Figs. 1

and 10,- secured to the shaft 21 and having a groove 56 in which is located a cam roll 57 journaled on the slide 52. The plate 44 is securedto a slide 58 mounted lto slide inVV suitable ways provided in the slide 52 and the slide 58 is reciprocated at the proper times in the operation of the machine by means of a cam 59 secured to the shaft 2l and having a groove 6() in which is located a cam roll 61 journaled on the slide 58.

In the operation of the bristle feeding andftuft forming mechanism, the needle 45 is lfirst advanced past the recess-or throat 47 and in so doing said needle engages a number' of bristles located in said recess and in advancing beyond saidlrecess, said needle doubles the bristles transversely thereof 'and forces them into the cylindrical passage 50, thus forming a tuft having a loop engaged by the needle. The tuft thus formed is carried'forward to a oint adjacent to the end or nose of the bristle carrier `41, said bristle carrier is then advanced to a point adjacent to the holder linto which the bristles are to be inserted, as will appear more fully hereinafter, and then the needle 45 is advanced within-thebristle carrier'tocarry the tuft out of the bristle carv rier into the bristle holder. Preferably,"the slide 52 has secured thereto a plate 62 which i's adapted to pass .between the guides 38 4and `39, and crowd t e mass of bristle'sin the bottom of the hopper toward the throat yor recess 47.

Tube feeding mechanism. (See 1,

2, 3, 7 and 12.)-A suitable metallic tube 63 passesbetween a pair of feed rolls 64 'and 65' securedx to shafts 66 and 67 vrespectively,vthe latter shaft' beingl journaled in suitable bearings68 and 69 provided on al slide v70 mounted tov slideI transversely of the longitudinal dimension of the tube 63 in ways 71 provided on a bracket 7 2secured to the base 24.- Thelshaft r 66 kis journaled slide 70.` Suitable compression springs 77 and 78 provided with adjusting screws 79 .-roll 64'to press the tube 63 against the feed roll '65 and assuring sufficient frictional'engagement so that the tube may be properly in bearingsl 73 and 74 mounted to slide vel- 4 tlcally 1n ways 75 and 76 provided on the y iis fed when the shafts 66 and 67 are rotated.

The shafts 66 and 67 are geared together by -gears 81- and 82 secured. to said shafts,"

respectively, and meshing with each other,

thus. causing said shafts to be rotated in f 'unison and the feed rolls 64 and 65 to be' positively driven at the same speed.

At the proper times inthe operation of the machine, the feed i'olls64 and 65 are roist ^ maar@ ltated to the proper extent to feed the tube therein by a collar 86 secured to said hub.

The ratchet 83 is provided at its opposite side with a hub 87 upon which a paWl carrying lever 88 is mounted to rock and held against longitudinal movement by a collar 89 secured to said hub.

Mounted upon the pawl carrier 88 is a feed paWl 90 engaging the teeth of the ratchet 83, see particularly Fig. 3, arranged to drive said ratchet in one direction, While a' stop pawl 91 (see Fig. 3) pivoted upon the bracket 85 and engaging said -ratchet'prevents reverse rot-ation thereof. The paw] carrier 88 is rocked at the proper times in the operation of the machine by a slide 92 (see Fig. 3) connected at its forward end to said pawl carrier by a pivot 93 (see Fig. 3) and having its rear end mounted to slidev in a suitable guidec 94 in Which it is capable of moving not only longitudinally, but vertically as Well so 'as to permit of a certain amount of rocking movement due to the |path of the pivot 93. The slide is reciprocated by a cam 95 secured to the shaft 21 and having a groove 96 in Which islocated a cam roll 97 journaled on said slide. Preferably, the slide 92 is formed, for Vthe purposes of adjustment, in two parts secured to each other by bolts 98 and 99, see Figs. 1 and '3.

That partuof the tube feeding mechanism which has already been described imparts an intermittent longitudinal feeding movement to the tube 63 at the proper times in the operation of the machine. At certain times in the operation of the machine, the tube is moved from right to left, Fig. 1, in orderl to presentvthe end of the tube -rst to the action of a bur-removing or chamfering means and then to the action of dies for compressing the walls of the tube, as Will appear hereinafter.` In order that the tube may be properly guided and held at thatend which is to be operated upon by these in-l strumentalities, there is' provided a guide 100, see particularly Fig. 1, secured to the slide v70. It will be evldent that since the slide is -to be moved to carry the feed left and viceversa, there must be provided a sliding connection between t-he shaft 67 'and the ratchet 83 and to this end said ratchet is provided with akey orfeather '101' arranged to slide in a key-1`vay 102 provided in said shaft. The slide'70 is recipro'- cated by a suitable mechanismpre'ferably comprisln a link 103`pivotally connected at one en to` said slide and at its'other end to a rocker arm 104, see4 particularly Fig. 2, Secured to a rock shaft 105. This rock shaft, which is journaled in suitable bear- I ings 106 on the base 24, is rocked at the proper'times in the operation of the machine by a cam 107 secured to the shaft 21 having .a groove 108 in which is located a cam roll 109 journaled on an arm 110 secured to said rock shaft.' By means of the tube feeding i mechanismhereinbefore described, the tube is fed longitudinall and presented to the action of the di erent instrumentalities which operate upon the same, as will be more fully described hereinafter.

Tube ekamferz'ng or bur-removing meehanz'sm. (See Figs. 1, 3 and'12).--In order thate the bur may be removed from the previously cut lend of the tube 63, there is provided a "suitable rotating 'chamferin'g tool 111, see particularly Fig. 12, suitably shaped to bevel or chamfer the inside of the end/of the tube and to also slightly chamfer the outside of said end, aswill be evident from an inspection-of'Fig. 12. This tool is mounted in a suitable holder or chuck con'- At the proper time in the operation of the machine', the slide 117 is carried forward and back to carry the chamfering tool toward and away from the end of the tube by .means of a cam 119 secured to the shaft 21 and-having a groove 120 in which is lo cated a'cam -roll 121 journaled on said slide. The shaft 112 is rotated by means of a belt 122 passing around a pulley 123 secured`to 'said shaft. When the tube 63 is presented at the proper time to be chamfered, the rotating chamfering tool is advanced'to the positlon shown in Fig. 12, the end of the tube is thus chamfered, and the chamfering tool recedes,'thus leaving the tube free to be carried toward the left, Fig. 12.

Tube compressing and z'ndentz'ng mecham'sm. (See Figs. 1, 2,5, 6,10, 13,' 14, 15, 18, 19 and 20.)-After the bur has been removed fr'om the end of the tube by chamferin the same, as hereinbefore described, the tube is carried from the position shown in Fig. 1 toward the left, a longitudinal feedi-ng movement is imparted thereto to bring the same into the position shown in Fig. 13, and the tuft is then ,inserted into the chamfered end of the tube in the manner shown in 13 by advancing the needle 45 into 1 thev position shown into the tube. After this has taken place, the end of the tubecontaining the tuft of Abristles is compressed and indented by the vfollowing mechanism.

.will be observed that groupe Referring now'r particularl consisting of the members 124 and 125 and the other pair consisting of the members 126 and 127,A all of which are mounted to slide radially in a circular die holder 128 and are given a longitudinal sliding movement therein by means of a ring 129 swiveled upon said die holder. This ring carries a plurality of arms 130, 131, 132 and 133 pivoted thereto and pivoted to the outer ends of the dies 124, 125, 126 and 127, respec tively, as shown in Fivs. 5 and 6. As this ring is rocked to and 2fro on the stationary die holder 128 by a mechanism which will be described hereinafter, the swinging arms just described act to impart to their respective dies a simultaneous movement toward the `tube and away from the tube. Preferably, the extremities of the dies where they engage the tube are substantially cylindrical in formv and also helical-or inclined at an angle to the axis of the tube 63. rlhe purpose of this helical form of the dies is to prevent the walls of the tube from being crippled to too great an extent by the throwing out of ribs between the dies. It will be seen that the size of these ribs would be increased. if the die faces were parallel to I the axis of the tube instead of' being inclined, as just described, or, in other words, the tube would be crippled to such an extent as to impair its power to liold the bristles. Preferably, areprovided, respectively, with spurs 134 and 135 which indent the tube and form in dentations 136 and 137 extending into the loop of the tuft in the manner illustrated in Figs. 18 and 19, particularly Fig. 19, thus locking the tuft within the tube. It is also highly desirable that the holder shall be compressed' around that portion which is I llocated between the indentations 136 and 137 and the end' of the tube from which the bristles proj ect and to this end the die mem.

bers 124, 125, 126 and 127 are provided, respectively, with more or `less abrupt shoulders 138, 139, 140 and 141, as best illustrated in Figs, 18 and 19, these shouldered portions of the diesserving to form a reduced portion or neck 142 firmly gripping the bristles adjacent to that end of the holder or tube' from which they project. Thus the.

entire operation of compressing the holder or tube and4 indenting the same is simul-l taneously accomplished by the simultaneous action of lall four of the die members.' The die actuatin ring 129 yis rocked to and fro l by any suita le means and for this purpose provide'said rlngwith a de- I preferably D ,143 connected by a link 144 tp pending arm the die membes 126 and 127 a rocker arm 145 secured to a rock shaft 146 journaled in bearings 147 -on the base 24. A rocking motion is imparted to the rock shaft 146 by means of a cam 148 secured tothe shaft 21 and having a groove 149 lin which is located a cam ,roll 150 journaled on an arm 151 secured to said rock shaft. l

Tube cutting of mechanism. (See Figs. 1, 2, 4, 12,13, 14 and 15.)-After the bristles have been inserted in the end of the tube and the end of the tube has been compressed and indented, as just described,.that portion of the tube which contains the bristles is cut off of the remainder of the tube by suitable means preferablyv consisting of a circular saw 152 which, as shown 1n Figs. 12 to 15, inclusive,=is placed adjacent to the front face of the dles 'and the die holder.

This saw is secured t0 a shaft 153 journaled in a suitable bearing provided in a rocker arm 154 secured to a rock shaft 155 mounted in suitable bearings .156 on the base 24. The shaft 153 has secured thereto a spur gear 157 meshing into a gear 158 secured to a shaft 159 also journaled in the rocker arm 154 and having secured thereto a pulley 160 driven by abelt 161 from overhead. The saw'is carried to and fro across the path of the tube 63 at the properv times in the operation of the machine by a cam 162 secured to the shaft 21 and having a groove 163 in which is located a cam roll 164 journaled on an arm 165 secured to the rock Vshaft 155.

By the mechanism just described, the tube is severed thus leaving a portion thereof forming a holder in which the bristles are firmly secured, the remainder of the tube being returned to its initial position to be op: erated upon by the bur-removingor chamfering mechanism. 4

, TaftA rejecting mechanism. (See Figs. 1, 4, 8, 9 and 10.)--Referring particularly to Fig. 9, 166 and 167 are grppers or jaws constituting pincers, to' each other by a pivot 168. The jaw 167 is provided with a rearwardly extending arm. 169, while the jaw 166 is prolonged,

said jaws being connected Y rearwardly to"form a slide 17 0 mounted in guides 171 and 172. This slide is carried forward and backward at the proper times in the operation of the machine by suit-able mechanismv as', for example, a link 173piv- .otally connected at one end to said slide and at its other end" toa lever 174, see Fig. 1,

provided with an angular slot 175 in which 1s located a pin 176 carried by the slide 52. The lever 174 is fulcrumed upon a standard 177, s eeFig. 10. The gripper 167 is rocked -upon its pivot 168 at the proper times in the operation of the machine by a device which is commonly known as a fourmotion feed and which comprises a plate 178 provided with a lateral recess 179 in which is located a stationary ide block A'180 and a pivoted switch -bloc 181, said i cess. The switch plate 181 may then drop by inclined surface 182. The arm 169 is pro vided with a laterally projecting pin 183 eX- tending into the lateral recess 179 and said arm is equipped with a suitable spring Y184 whose tendency is to keep the jaws 166 and 167 closed. When, however, the rslide 170 is retracted from the position shown in Fig. 9, the pin 183 travels along the bottom of the recess 179 up the inclined surface 182, thereby displacing the switch plate 181 and arriving at the extreme right hand end of said regravity or it-may be provided with a spring 185 connected to an arm 186v secured to a rock shaft 187 to which the switch plate 181 is also secured. This spring assures the return of theV switch plate to the position shown in Fig. 9, after the pin 183 has passed therebeyond; j When this has occurred, it is evident that the jaws 166 and 167 will be opened, since by this action the arm 169 has been rocked upwardly from the` position shown in Fig. 9. When this has taken place, the next forward motion of the slide 170 acts to carryt-he pins 183 along the top of the switch plate 181 and the stationary block 180 and said pin is returned by the spring 184 to the position shown in Fig. 9. lWhile the compressing, indentingand sawing of thetube is taking place, the grippers 166 and 167 are advanced by the mechanism just described into the position /shown in Fig. 9 and grip the bristles, as shown in said figure and as shown in Figs. 12 and 15. As soon as the dies open andl release the bristle holder, the grippers recede from the position shown in Fig. 9 and open', thus dropping the tuft onto a chute 188, see Figs. 1 and 4. Sometimes the bristles have a tendency vto stick to the grippers and 4would not be released with certaintyl and, accordingly, I provide a plate 189, see Figs. 1 and 9, secured to the wall 2 8 of the hopper 26 and eX- tending to a point adjacent to the top of the gripper 166, as shown in Fig. 9. When` the grlppers recede' from the position shownin Flg.

bur-removing or chamfering mechanism, the

inside of the end of the tube is chamfered,

the tube is then carried into a position be tween the dies and' thus presented. to the actionof the .tuft inserting mechanism. A set of bristles is taken from the mass in the hopper and bent transversely to form a tuft A having a loop by the coperative action ofthe needle and bristle carrier.` The bristle carrier is then advanced to a point adjacent to the end of the tube, as shown in Figs. 13 and 14, the loop of the tutt is inserted in the chamfered end of the tube, the tube is then compressed and indented, and that portion of the tube which contains the tutt is cutotl' from t-he remainder of the tube, thus leaving the bristle holder held by the dies. The grippers of the ejecting mechanism having gripped the bristles of the tuft, the dies open and release the finished tutt and the same is then removed from the dies and dropped onto the chute. The parts then return to their initial positions ready for another operation.
